Tournament

Even though numerous nations enter the Fed Cup each and every year, only 16 countries qualify for the elite Globe Group and Globe Group II each year (eight in Globe Group and eight in Globe Group II).

They reach Globe Group and World Group II as follows:

(a) World Group – the 4 nations that win their World Group very first round tie stay in the world Group for the following year. 1st round losers contest the World Group Play-offs against the four winning nations from World Group II to decide relegationpromotion for the following year’s competition. (The 4 nations that win World Group Play-offs are going to be in the world Group the following year, even though the four losers will commence the following year in Globe Group II.)

(b) Globe Group II – the 4 nations that win their World Group II ties will compete in the world Group I Play-Offs to figure out relegationpromotion for the following year Nike Air Max 97 Günstig , as described above. Similarly the four nations that lose their Globe Group II ties will face winning nations from Group I Zonal competitions, on the planet Group II Play-offs, to identify relegationpromotion. (The 4 nations that win their World Group II Play-offs are going to be in World Group II the following year, whilst the four losers will begin the subsequent year in Group I Zonal events.)

Once on the planet Group or World Group II, four nations will be seeded in every. The decision as to which nations will be seeded is produced by the Fed Cup Committee, based on the ITF Fed Cup Nations Ranking.

At the levels below the World Group and Globe Group II Nike Air Max 96 Günstig , the Fed Cup nations compete in Zonal Competition events, which are split into 3 zones: The Americas Zone, the AsiaOceania Zone plus the EuropeAfrica Zone.

CHICAGO Nike Air Max 95 Damen Günstig , Sept. 19 (Xinhua) -- Mothers in China are not passing on protective antibodies against measles to their infants, leaving children under 8 months vulnerable to the disease, researchers at the University of Michigan (UM) have found.

Moreover, the level of protective antibodies decreased with age, with almost all infants lacking maternal antibodies at 3 months old.

The study shows that current vaccination programs are not effective in controlling transmission of measles to infants, said Matthew Boulton Nike Air Max 95 Herren Günstig , senior associate dean for global public health at UM School of Public Health. He suggests the infants or their mothers may need additional protection.

The 2011-2015 study involved 551 infants aged one to eight months old and their mothers from 120 rural villages and urban communities representing each of the 16 geographic districts in Tianjin in northeastern China.

Research has shown that when a pregnancy goes full term and the mother has adequate nutrition, she will typically pass on antibody protection to the fetus if she has been immunized or has had a case of the measles.

The current study showed mothers with a known history of measles provided 1.6 times higher titers, the concentrations of antibodies in the blood, to their infants than those mothers who had no known history with the disease or vaccination; over two-thirds of mothers who were immune to measles were unsure if they had been vaccinated or had disease.

Although infant deaths have decreased by 79 percent since 2000, measles continues to be one of the most infectious diseases in the world, and claimed more than 134 Nike Air Max 95 Grün Günstig ,000 lives worldwide in 2015, mostly infants and young children. And a large percentage of measles cases continue to occur in China.

In China, children usually receive the first dose of measles vaccine at 8 months, and the second dose at 18-24 months.

"China has been very successful at immunizing eligible children for measles and for carrying out very large Special Immunization Activities (e.g., National Immunization Days), which have resulted in literally millions of children being vaccinated for measles in a short period of time Nike Air Max 95 Rosa Günstig ," Boulton said.

"Despite these successes, measles continues to occur at unacceptably high rates in both young infants and adults, which points to the need for new approaches, including the possibility of launching organized campaigns to immunize young women of reproductive age," Boulton said.
